The agency's news release said 55-year-old finish sander Tom Hegg died on Jan. 13, 2015, after acute exposure to wood dust during his 15 years with the company. OSHA then launched an investigation at the site, and inspectors found 21 serious safety violations. The company faces a proposed fine of $50,000.

"Oak Creations could have implemented simple, common-sense measures to provide a safe workplace for employees," said Eric Brooks, OSHA's area director in Billings. "The best way to honor Mr. Hegg is to ensure that his colleagues have a safe place to work."
